Answer:
1. No
2. Yes
3. Yes
4. Yes
Step-by-step explanation:
In 1. the difference between each term is not constant.(it goes up by, 2, 4, 6)
2. The terms increase by the same amount(it all goes up by 3)
3. The terms decrease by the same amount(it all goes down by 5)
4. The terms increase by the same amount(it all goes up by 6)
Answer:
Step-by-step explanation:
The area is the product of the length and width
- The area = 7 1/6 m² = 43/6 m²
- The length = 3 1/3 m = 10/3 m
Width = ?
- A = lw
- w = A/l
- w = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 m
The width is 2 3/20 m
Answer:
Mean of the population having 6"-9" Hatching =38
Standard Deviation =4
Step-by-step explanation:
Confidence interval of 95% means that 95% of data lie within two standard deviations.
That is data values lie between 38-2×4 to 38 +2×4.
⇒Which is 38-8 to 38+8.
⇒30 to 46.
it is also given that margin of error is 2.5%.
So, the data value will lie between
Mean of beginning value to extreme value of 95% confidence level
So, Sample mean of this observation having 2.5% margin of error = 38
Option D:→ 38
Answer:
Yes because 5^2 + 12^2 = 13^2
Step-by-step explanation:
We can check using the Pythagorean theorem
a^2 + b^2 = c^2
5^2 + 12^2 = 13^2
25+ 144= 169
169 = 169
Answer:
(B) 
Step-by-step explanation:
A polynomial is the expression which consists of addition, subtraction, multiplication with any variables or constants but the division with a variable is not considered as a polynomial.
Since consists of division of -3 with a variable, therefore it is not a polynomial, rest all other options are polynomial as they involve addition,multiplication with variables.
